Grass Valley REF-1801-3RU Reference Module with Optional Generator

Grass Valley, REF-1801-3RU, Reference Module with Optional Sync Pulse Generator for Densite 3 Frame

The REF-1801 from Grass Valley, a Belden Brand, is a reference module that distributes a universal reference signal (URS) to all the cards within a Densite frame. It can also optionally generate two selectable reference signals for external use. The unique URS concept provides significant advantages as it generates a digital reference signal, and also simplifies interformat processing by using a unique reference signal for all video and audio frame rates. The REF-1801 has the ability to extract timecode from the input as per SMPTE-318M, which allows for perfect audio/video phasing. Other features include the ability to slave Densite frames, as well as advancing or delaying independently the two reference output signals.

Features:

• Digitally generated reference for intraframe distribution
• Timecode extraction and embedding
• Supports SMPTE-318M for perfect audio/video phasing
• Easy control and monitoring
• URS simplifies interformat processing
